But when she was just 6 weeks old, she went into heart failure. "I had to have a heart transplant when I was 18 months old, after living at the Hospital for Sick Children for 3 1/2 months," she says. "I am doing really well now.I have to take good care of this precious heart, because I am so very lucky to have it."

When Sarah realized that many perfectly healthy organs don't get used, she was shocked. So now she's started an organ donation drive to raise awareness. "Nobody knows when somebody we love might need an organ transplant," she says. "I asked my mom what it was like to be hoping somebody else's child died so that I could live, but she explained that it's not like that at all. Bad things happen all of the time—she just hoped and prayed that no organ would be wasted, and if one was available, they would decide to help me live."
